swissTLM3D is the large-scale topographic landscape model of Switzerland. It includes both natural and artificial landscape features, as well as name data in vector form. With a high degree of accuracy and the incorporation of a third dimension, swissTLM3D is the most extensive and accurate 3D vector dataset of Switzerland.


The large-scale topographic landscape model of Switzerland

Version 2.1

swissTLM3D is available for all of Switzerland and the Principality of Liechtenstein. The current release has the version name swissTLM3D 2.1. A PDF document containing a full overview of the swissTLM3D 2.1 data catalogue, including a list of modifications made in comparison to swissTLM3D 2.0, is available in German or French.

News from swissTLM3D

The 2023 edition of swissTLM3D is now also available in GeoPackage format and contains all validated street names from the official index of streets.


swissTLM3D can be used for a wide range of applications thanks to its simple and clearly defined landscape feature structure:

  • as a reference data set for establishing information systems (e.g. dynamic segmentation based on the road network of swissTLM3D)
  • as a basis for 3D visualisations and analyses (depending on the application, in conjunction with swissALTI3D)
  • as a database for simulations, plans and statistics
  • as a starting point for publications (maps, plans, Internet) and finished products (e.g. multimedia, navigation or geomarketing)

Additional information

Technical details


swissTLM3D describes more than 20 million landscape features, together with their position and shape, the corresponding landscape feature type and many other attributes. swissTLM3D comprises of 8 topics, each of which contains one or more feature classes.

Roads and tracks

Road and path networks

Public transport

Railway lines and other rail systems, shipping routes and public transport stops


Buildings, walls, dams, constructions relating to transport, communication, energy, sport and leisure


Plots with special land usage (transport, nature, habitat, leisure, etc.)

Land cover

Ground coverage independent from land usage


Watercourses and lake contours

Single point objects

Selection of prominent landscape features which aid orientation (crossings, sources, caves)


Various names (mountains, areas, towns, etc.)

File formats

swissTLM3D is available in the following file formats:

  • ESRI File Geodatabase
  • ESRI Shapefile
